Optimizing memory by sharing datasets between workspaces

ABSTRACT

Methods and system are disclosed that optimize memory consumed, by sharing datasets between workspaces. In one aspect, multiple workspaces may be instantiated by retrieving multiple datasets from multiple data sources. An input to execute transformations on the multiple datasets may be received. Based on a determination of execution of a transformation on the multiple datasets, a dataset context analyzer may be executed to analyze a current context of data in the multiple datasets. Based on a result of execution of the dataset context analyzer, a transformation graph analyzer may be executed to compute a current context of transformations on the multiple datasets. Based on the determined current context of data and the current context of the transformations on the dataset, memory consumed may be optimized by sharing the multiple datasets between the multiple workspaces.

BACKGROUND

Multi-tiered software applications may include multiple integrated components with distinct and unique functionalities. Such software applications may provide instances of workspaces to execute the functionalities or operations on data. When instances of workspaces are generated, a local copy of each instance of the workspace may be created. Sharing data between local copies of each instance of the workspace may be cumbersome. Further, maintaining or tracking changes in the data may be challenging, when multiple users may access the same data via the instance of workspace. Determining modifications of the data with reference to context and sharing the data between the instances of the workspaces, thereby optimizing memory consumed, may be challenging.

DETAILED DESCRIPTION

Embodiments of techniques related to optimizing memory by sharing datasets between workspaces are described herein. In the following description, numerous specific details are set forth to provide a thorough understanding of the embodiments. One skilled in the relevant art will recognize, however, that the embodiments can be practiced without one or more of the specific details, or with other methods, components, materials, etc. In other instances, well-known structures, materials, or operations are not shown or described in detail.

Reference throughout this specification to “one embodiment”, “this embodiment” and similar phrases, means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one of the one or more embodiments. Thus, the appearances of these phrases in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

Volume of enterprise data may grow exponentially with time. In such a scenario, managing storage and access to the data may become challenging and may add to the complexity of existing infrastructure. Further, enterprise applications and systems may access and modify the data. Devising mechanisms to track such modifications in the data may further add to the complexity of storage, maintenance and access to the data.

The enterprise applications and systems may provide integrated environments including workspaces for accessing and modifying the data. The data may be retrieved onto local systems into instances of workspaces. Each instance of workspace may be independent and unique to the local system. A workspace may correspond to an integrated development environment (IDE) including resources (e.g., editors, compilers, assemblers, etc.) for developing software applications or products. The IDE may communicate with multiple distributed data sources over a network (e.g., Internet). The data stores may store the data in multiple formats (e.g., .xls, .csv, .doc, .txt, .ppt, etc.) and may be represented as datasets. When such datasets are retrieved by the IDE, an instance of workspace may be instantiated and a corresponding workspace context may be created.

A workspace context may be unique and may limit the modifications on a dataset. For example, when dataset X is retrieved into workspace A, the access and modification on the dataset X is restricted to workspace A. When data in the dataset X is modified via workspace A, the access to the data modifications may be restricted to workspace A. A copy of the dataset X may be created that may be accessed by another workspace, e.g., workspace B. In an embodiment, creating multiple copies or instances of the data may be redundant and may lead to increase in memory consumed for storing such data. Therefore, by tracking the contexts of data modifications, it may be possible to share the datasets between multiple users (or respective workspaces, for example, dataset X may be shared between workspaces A and B). Such sharing of the datasets may optimize memory consumption and the performance (e.g., functional efficiency) of the workspaces. In an embodiment, optimizing may correspond to improving performance of workspaces, amount of memory consumed for storing multiple datasets in the data sources, etc. Therefore, the memory consumed by the datasets may be reduced, when the datasets are shared between the multiple workspaces.

FIG. 1 is a block diagram illustrating environment 100 to optimize memory by sharing datasets between workspaces, according to an embodiment. FIG. 1 shows workspace 102 including multiple datasets (e.g., 104, 106, 108, 110, 112, 114, etc.) that may be associated with corresponding data sources (e.g., 104A, 106A, 108A, etc.). Upon instantiating workspace 102, datasets (e.g., one or more of 104, 106, 108, 110, 112, 114, etc.) may be retrieved from the respective data sources. In an embodiment, datasets (e.g., 104, 106, 108, 110, 112, 114, etc.) may be associated with multiple attributes or parameters represented as measures, dimensions, visualizations, text/images, shapes, etc. (e.g., 104B, 104C, 104D, 106B, 106C, 106D, 108B, 108C, 108D, 110A, 110B, 110C, 112A, 112B, 112C, 114A, 114B, 114C, etc.).

In an embodiment, when datasets (e.g., 104, 106, 108, 110, 112, 114, etc.) are retrieved, workspace 102 may be instantiated and a workspace context may be created. The workspace context may define contextual boundary that may restrict the modification of data in the datasets (e.g., 104, 106, 108, 110, 112, 114, etc.) within the context of workspace 102. The workspace contexts may be used to control a state of an application workspace. For example, when a user instantiates the workspace, controlling the state of the application workspace may correspond to controlling data or objects including data in memory (e.g., schema, transformed data, etc.). In an embodiment, controlling the state of the application workspace may restrict an access of the data or objects within a context of application workspace.

In an embodiment, when multiple workspaces are instantiated, correspondingly multiple workspace contexts may be created. When identical datasets (e.g., same datasets are retrieved from the same data sources) are retrieved into the multiple workspaces, the datasets (e.g., 104, 106, 108, 110, 112, 114, etc.) may be correspondingly restricted to the specific contexts of the multiple workspaces. When a user executes transformations (e.g., modify, add, delete, append, etc.) on datasets (e.g., 104, 106, 108, 110, 112, 114, etc.), the transformations may create multiple transformation contexts for the datasets (e.g., 104, 106, 108, 110, 112, 114, etc.). In an embodiment, current context of data in datasets (e.g., 104, 106, 108, 110, 112, 114, etc.) and a current context of transformation on datasets (e.g., 104, 106, 108, 110, 112, 114, etc.) may be determined. Based on such determination, a decision logic associated with the workspace may determine whether datasets (e.g., 104, 106, 108, 110, 112, 114, etc.) may be shared between multiple workspaces.

In an embodiment, multiple algorithms may be executed and work in cooperation with the workspaces to determine the current context of datasets and the current context of transformations on datasets. For example, to determine the current context of datasets, a routine (e.g., set of instructions executed by a processor of a computer) related to dataset context analyzer 116 may be executed. The execution of the routine related to the dataset context analyzer 116 may determine the current context of data in the datasets. Based on the response of the dataset context analyzer 116, a routine related to transformation graph analyzer 118 may be executed. The execution of the routine related to the transformation graph analyzer 118 may compute the current context of the transformation on datasets. In an embodiment, based on the determined current context of the data and the current context of the transformations of data in datasets, a routine related to dataset manager 120 may determine whether the datasets may be shared between the workspaces. For example, the decision logic to determine whether the datasets may be shared between the workspaces may include determining whether the datasets have the same measures and dimensions, determining whether the datasets are from the same sources (e.g., data stores, databases, etc.), whether the datasets are equal or include common subsets. Based on such determinations, a dataset manager associated with the workspace may determine whether to share the datasets between the workspaces. In an embodiment, when the datasets are shared between the workspaces, memory consumed by datasets is reduced and hence the performance of the workspaces may be optimized.

FIG. 2 is a flow diagram illustrating process 200 to optimize memory by sharing datasets between workspaces, according to an embodiment. When multiple datasets are shared between multiple workspaces, memory consumed may be reduced and the performance of the multiple workspaces may be optimized. In an embodiment, upon instantiating workspaces, datasets are retrieved from data sources into the workspaces, at 210. Multiple datasets may be retrieved into the workspaces from multiple data sources. The datasets may be associated with attributes or parameters such as, measures, dimensions, visualizations, etc. In an embodiment, a measure may correspond to a property on which calculations may be executed. Dimensions may correspond to structures that may categorize the measures. Visualizations may correspond to converting data into visual representation. In an embodiment, when datasets are retrieved from data sources into the workspaces, a corresponding workspace contexts may be created.

In an embodiment, inputs to execute transformations on datasets is received, at 220. The received inputs may correspond to executing transformations on the data in the datasets including modifying (e.g., edit, delete, add, append, etc.) the data or dimensions of the data by a user. For example, the user may execute transformations for adding or appending data to the datasets, deleting data from the datasets, modifying content in the datasets, etc. Such transformations on the datasets may be determined and based on such determination, the current context of the data in the datasets is analyzed, at 230. For example, the current context of transformation on the datasets may be determined by comparing the original dataset (e.g., before transformation) with the current dataset (e.g., after executing transformations). In an embodiment, the current context of the data in the datasets is analyzed by a dataset context analyzer (e.g., routine related to dataset context analyzer may be executed by a processor of a computing system).

In an embodiment, based on the dataset context analysis, a current context of the transformation on the datasets is computed, at 240. In an embodiment, a transformation graph analyzer (e.g., routine related to transformation graph analyzer may be executed by processor of the computing system) may be executed to compute the current context of the transformations on the datasets. The current context of the transformations on the dataset may indicate type of transformation, number of transformations, etc., that may be executed on the datasets. For example, type of transformations may include duplicating dimensions associated with the dataset, deleting dimensions associated with the dataset, renaming dimensions associated with the dataset, etc. Based on a determination of the current context of the data in the datasets and the current context of the transformations on the datasets, the multiple datasets may be shared between the multiple workspaces. For example, as discussed previously, the decision logic to determine whether the datasets may be shared between the workspaces may include determining whether the datasets have the same measures and dimensions, determining whether the datasets are from the same sources (e.g., data stores, databases, etc.), whether the datasets are equal or include common subsets. In an embodiment, based on the current context of data in the datasets and the current context of the transformations on the datasets, the datasets are shared between the workspaces, at 250. In an embodiment, the datasets may be shared between the workspaces based on a decision logic and such sharing of the datasets between the workspaces may optimize the memory. For example, the decision logic may include determining whether the current context of the transformations on datasets are equal or not in two or more workspaces. In an embodiment, when the current context of the transformations on datasets between at least two workspaces are determined to be equal, the datasets may be shared between the workspaces, e.g., by a dataset manager. The sharing of datasets between multiple workspaces may optimize the performance of the workspaces, optimize the memory consumed by the datasets, etc.

In an embodiment, the execution of routine related to dataset context analyzer may analyze a current context of the data in the datasets. The dataset context analyzer may analyze the context of data in the datasets before the execution of the transformations, after the execution of the transformations, etc., and generate a result of the analysis. The analysis may include a comparison of the contexts of data (e.g., before the execution of the transformations, after the execution of the transformations, etc.) and the result of analysis (e.g., ‘similar’, ‘different’, ‘equal’, etc.) may be generated. When the result of the analysis is determined as ‘different’, it may be represented by delta that may correspond to a degree of change in contexts of the data. In an embodiment, the dataset context analyzer may further analyze by comparing the contexts of the data in the datasets to determine whether the datasets (e.g., D_(S1) and D_(S2)) are retrieved from same data source (e.g., identical data sources D_(X1) and D_(X2); that is, whether D_(X1)=D_(X2)); determine whether the attributes (measure, dimensions, etc.) associated with the datasets are same (e.g., identical); determination of the data in the datasets, before and after the transformations, etc.

In an embodiment, upon instantiating two workspaces (e.g., A and B), consider that a dataset (e.g., dataset X, a spreadsheet file including data in a matrix of cells of rows and columns) is retrieved from a data source into the two workspaces. Correspondingly, two workspace contexts may be created and the dataset context analyzer may be executed to determine the current context of the data in the dataset on the retrieved dataset X. In an embodiment, consider that a first user via workspace A executes transformations (e.g., add, delete or modify data in one or more cells, one or more rows, one or more columns, etc.) on the dataset X and saves these transformations, which may be stored in the data source. In a subsequent interval of time, consider that second user accesses dataset X via workspace B. In an embodiment, the dataset context analyzer may be executed to analyze the context of data in the dataset X. The first and second user may access and work on the shared dataset X, which may include the transformations executed by the first user via workspace A Since the dataset X was previously accessed by the first user via workspace A and transformations were executed, the execution of dataset manager may determine that the context of data in the dataset X is now changed (e.g., by comparing the contexts of the data with the original dataset X). In an embodiment, the dataset X including transformed data may correspond to a current context of the data.

In an embodiment, based on the result of the determination of the current context of the data, the transformation graph analyzer may be executed to compute the current context of the transformations (e.g., the changes or modifications on the data) in the dataset (e.g., by comparing the original dataset X and the dataset X including transformed data). When the current contexts of the dataset in the two workspaces and the current context of transformation (e.g., delta, which may correspond to change based on transformation) are equal (e.g., same or identical, based on the decision logic, as discussed above), the dataset X may be shared between the two workspaces (e.g., A and B) and a reference count associated with the dataset may be set to 2. When a user stops accessing the dataset from one of the two workspaces (e.g., A or B), the reference count associated with the dataset may be decreased to 1. When users stop accessing the datasets from the instantiated workspaces (e.g., both workspaces A and B), the reference count associated with the dataset is decreased to 0. In an embodiment, when the current context of data and the current context of transformation are not equal, the dataset X may not be shared between the two workspaces.

In an embodiment, when a transformation is executed on the dataset that is shared between two or more workspaces, the dataset may be forked (e.g., different contexts of datasets may be generated). The forking of the dataset may correspond to generation of a new context of the dataset including the original data, when the transformations are executed in a workspace from the two or more workspaces where the dataset is shared. When the datasets are forked, the original data in the datasets may be replicated and the users of the two or more workspaces may correspondingly access and work (e.g., execute transformations) on the forked datasets. In an embodiment, the dataset manager may determine an event of forking of the dataset, and may stop sharing the datasets between the workspaces. Local copies of the datasets may be created that may be accessed by respective instances of the workspaces.

FIG. 3 is a block diagram illustrating instantiation of multiple workspaces by retrieving multiple datasets from multiple data stores, according to an embodiment. FIG. 3 shows instantiation of multiple workspaces (e.g., 302, 304, 306, and 308) by retrieving multiple datasets (e.g., 310, 312, 314, and 316) from multiple data sources. In an embodiment, corresponding multiple workspace contexts may be created and the workspace contexts or multiple workspaces (e.g., 302, 304, 306, and 308) may work in cooperation with a dataset manager 318. As discussed previously, the dataset context analyzer may be executed to determine the current context of data in multiple datasets (e.g., 310, 312, 314, and 316). Based on the response of the execution of the dataset context analyzer, the transformation graph analyzer may be executed to compute the current context of transformations on the datasets. When the current context of the data and the current context of transformations on the datasets are determined as equal (e.g., based on the decision logic and comparison of the datasets (the original dataset and the dataset including transformation), dataset manager 318 may share the datasets between one or more workspaces (e.g., FIG. 3 shows dataset 314 is shared between workspaces 306 and 304 indicated by an arrow). In an embodiment, such sharing of the datasets between the workspaces may optimize the performance of the workspaces and the memory consumed by the datasets and the workspaces.

FIG. 4 is a block diagram illustrating execution of multiple transformations on a dataset, according to an embodiment. FIG. 4 exemplary illustrates the execution of multiple transformations (e.g., transformation 1 410, transformation 2 412, transformation 3 414, etc.) on dataset 1 DS 402. When transformation 1 410 is executed on dataset 1 DS 402, dataset 1 DS (T1) 404 may be generated. Sequentially, when transformation 2 412 is executed on dataset 1 DS (T1) 404, dataset 1 DS (T2) 406 may be generated, when transformation 3 414 is executed on dataset 1 DS (T2) 406, dataset 1 DS (T2) 408 may be generated, and so on.

In an embodiment, let dataset 1 D₁ be associated with a data source D_(X1) where the original dataset context is represented by DS_(1x). For example, when the following transformations are executed on dataset 1 D₁: T ₁: duplicate a dimension d ₁ such that DS _(1X) transforms to DS _(1X) T ₁  Equation (1) T ₂: delete a duplicate dimension such that DS _(1X) T ₁ transforms to DS _(1X) T ₂  Equation (2) T ₃: rename a dimension d ₂ such that DS _(1X) T ₂ transforms to DS _(1X) T ₃  Equation (3)

In an embodiment, upon executing the above transformations, the current context of the dataset may be represented by: DS _(1X) T ₃ =DS _(1X) +T ₁ +T ₂ +T ₃  Equation (4)

In an embodiment, the delta or change in context of the data, when the transformations are executed, may be computed by: delta 1(T ₁ +T ₂ +T ₃)=DS _(1X) T ₃ −DS _(1X)  Equation (5)

FIG. 5 is a block diagram illustrating execution of a transformation on a dataset, according to an embodiment. FIG. 5 illustrates an execution of a transformation (e.g., transformation 1 506) on a dataset (e.g., dataset 2 DS 502). When transformation 1 506 is executed on dataset 2 DS 502, dataset 2 DS (T1) 504 may be generated.

In an embodiment, let dataset 2 D₂ be associated with a data source D_(X2) where the original dataset context is represented by DS_(2x). For example, when the following transformations is executed on dataset 2 D₂: T ₁: rename a dimension D ₂ such that DS _(2X) transforms to DS _(2X) T ₁  Equation (6)

In an embodiment, upon executing the above transformation, the current context of the dataset may be represented by: DS _(2X) T ₁ =DS _(2X) +T ₁  Equation (7)

In an embodiment, the delta or change in context of the data, when the transformations are executed, may be computed by: delta 2(T ₁)=DS _(2X) T ₁ −DS _(2X)  Equation (8)

In an embodiment, based on the decision logic, as discussed previously, the dataset manager may determine whether delta 1 is equal to delta 2 (e.g., from equation (5) and equation (8)). In an embodiment, when the dataset manager determines that the current context of data and the current context of transformations on the datasets are equal, the dataset manager may share the datasets D₁ and D₂ between workspaces. Sharing the datasets may optimize the performance of the workspaces and the memory consumed by the workspaces. In an embodiment, when the current context of the data and the current context of transformation on the data are not equal, the dataset manager may determine that delta 1 is not equal to delta 2, and accordingly the dataset manager may not share the datasets between the workspaces.

Some embodiments may include the above-described methods being written as one or more software components. These components, and the functionality associated with each, may be used by client, server, distributed, or peer computer systems. These components may be written in a computer language corresponding to one or more programming languages such as functional, declarative, procedural, object-oriented, lower level languages and the like. They may be linked to other components via various application programming interfaces and then compiled into one complete application for a server or a client. Alternatively, the components maybe implemented in server and client applications. Further, these components may be linked together via various distributed programming protocols. Some example embodiments may include remote procedure calls being used to implement one or more of these components across a distributed programming environment. For example, a logic level may reside on a first computer system that is remotely located from a second computer system containing an interface level (e.g., a graphical user interface). These first and second computer systems can be configured in a server-client, peer-to-peer, or some other configuration. The clients can vary in complexity from mobile and handheld devices, to thin clients and on to thick clients or even other servers.

Storage 610 provides a large space for keeping static data where at least some instructions could be stored for later execution. According to some embodiments, such as some in-memory computing system embodiments, RAM 615 can have sufficient storage capacity to store much of the data required for processing in RAM 615 instead of in storage 610. In some embodiments, all of the data required for processing may be stored in RAM 615. The stored instructions may be further compiled to generate other representations of the instructions and dynamically stored in RAM 615. Processor 605 reads instructions from RAM 615 and performs actions as instructed. According to one embodiment, computer system 600 further includes output device 625 (e.g., a display) to provide at least some of the results of the execution as output including, but not limited to, visual information to users and input device 630 to provide a user or another device with means for entering data and/or otherwise interact with computer system 600. Each of these output devices 625 and input devices 630 could be joined by one or more additional peripherals to further expand the capabilities of computer system 600. Network communicator 635 may be provided to connect computer system 600 to network 650 and in turn to other devices connected to network 650 including other clients, servers, data stores, and interfaces, for instance. The modules of computer system 600 are interconnected via bus 645. Computer system 600 includes a data source interface 620 to access data source 660. Data source 660 can be accessed via one or more abstraction layers implemented in hardware or software. For example, data source 660 may be accessed by network 650. In some embodiments data source 660 may be accessed via an abstraction layer, such as a semantic layer.
